The E-T-A 3120-N523-P7T1-W02D-4A is a thermal circuit breaker that combines overcurrent protection with the function of an ON/OFF switch. It utilizes a bimetal trip element and is suitable for overload protection of motors, pumps, transformers, and cables. This 2-pole breaker has a current rating of 4A and a voltage rating of 415V AC or 50V DC.
Designed for panel mounting with a rocker actuator, this circuit breaker offers reliable disconnection and easy resettability after tripping. Its applications include apparatus and machine construction, professional tools, and household appliances. The device is approved by CSA, GB, IEC, and UL standards.
Further functional extensions are possible with add-on modules for low voltage release, auxiliary contact function, remote trip, or fast magnetic trip. It is also suitable for use in medical equipment according to IEC/EN 60601.
